NOEL J. POUX, F HEA'DVILLE, PENNSYLVANIA, AS$IGNOB TO LION FASTENER INC OI IEADVILLE, PENNSYLVANIA, A CORPORATION OF DELAWARE SEPABABLE FASTENEB Application filed September 18, 1829. Serlal No. 892,785.

It is desirable with separable fasteners in many relations tohave as little of the operating elements of the fastener exposed as possible. The'present invention is designed a to improve the fastener along this l1ne.- It

is also desirable to reduce the size and projection of the confining plateof the slideroperating on the fastener and the present invention is designed to accomplish this parpose. Further features and details of the invention will appear from the specification and claims.

Preferred embodiments of the invention are illustrated in the accompanying'drawings as follows i Fig. 1 shows a separable fastener with the slider in place thereon.

Figs. 1 to 4 inclusive, 1 marks the stringers.

These are provided with ribs 2. The ribs are preferably ofi-set, that is to say, as

- shown each 119 is formed at one side only of the string r Interlocking, onfastener members 3 are provided with interlocln'ng projections 4 and cavities 5 receiving these projections. The

members are each provided with an opening 6 which is designed toreceive the rib.

A jaw 7 operates on one side of the opening and a jaw 8 on the opposite side. The rib is placed in the opening and the jaws closed.

The jaw 8 is shorter than the jaw 7 being in the form of the invention shown inpreferably of less length than the recess 6. The inner surface 9 of this jaw is ofi-set slightly from theplane 10 of the same side of the stringer and the jaw 7 isprovided with the projection 11 engaging the rear of the rib and also deflecting the free portion of the stringer toward the opposite edge of the fastener thus making the engagement somewhat more efi'ective and at the same time reducing the exposure of the narrow part of the fastening members. As the jaws 7 and 8 areclosed from either initial dotted position, as shown in Fig. 2, the rib is clamped between the surface 9 of the short jaw and the surface 12 on the jaw 7.

The interlocking members project from the edges of the stringers and the free part of each of the stringers, that is, the part eff the stringer outside of the clamps is ofi-set relatively to the edges 3c of its interlocking members. Thus there is less projection of the interlocking members from the face of the stringer toward one edge of the members than from the face of the stringer toward the o posite edges of themembers and the side aving the lesser projection is consequently made less conspicuous and ofiers less obstruction. It will also be noted that the exposed edges of the interlocked fasteners form very well-defined strips along the opposite -aces of the stringers, said strips being usualiy contrasted in color from the stringers themselves and that the strip on the side having the jaws 8 is very materiall narrower than that on the side having t e jaws 7. This feature supplementing the lesser projection of the jaws 8 also tends to make this side of the fastener as inconspicuous as possible. On the other hand the jaw 7 is of sufiicient length to properly engage the rib of the stringer and the projection 11 is closed back of the rib, thus positively locking the fastener to the stringer. Also the shoulder formed by the outer ends 76 of the jaws 7 give ample engagement to the guiding means of an attached slider so that notwithstanding the small projection of the jaws 8 there isa-n assured guiding action of the slider throu' h the greater contact on the ends 7e of e which is bent inwardl jaws 7. This greater depth of shoulder at the ends 7e of the jaws 7 makes it possible also to provide a slider with guiding flanges only at the side enga ing the ends 70.

In Figs. 5 6 and 7 show a modification. The interlocking members 3a have cavities 5a with correspcnding projections (not shown) similar to the cavities 5 and proections 4, and a rib-receiving recess 60.

he jaw 7a has an upturned end 11a which is ointed so as to netrate the material. This pointed end is nt downwardl preferably to a point under the end of t e jaw 8a, as clearly shown in Fig. 7. This is brought about by first bending the jaw 11a to the position shown in Fig. 7 and then bendin down the jaw 8a.

In h ig. 8 I show another modification in which the interlocking member 3?) has the cavity 5b with a projection (not shown) similar to the projection 4. It is rovided with a recess 61) receiving the rib (1 end. The jaw 7 b has the elongated upturned portion 11?) which is bent over the rib 2, thus making a restricted space between the end of the projection 11b and the shoulder 86 on the member. Thus the ribbed. edge is securely locked in place and the material is given a definite rearward turn.

In Fig. 9 a modification is 'shown in which the member has the recess and a projection (not shown) corresponding to the projection 4. The recess receives the rib and the jaw has the projection 110 over the rib. The short jaw is bent. ownwardly over the return bend of the stringer and thus securely looks it in place.

In Fig. 10 the modification has a member 3d with a recess 5d and a projection (not shown) corresponding to the rejection 4. It is rovided with a recess 6d or receiving the ribbed edge of the stringer. The long jaw 7d has an upward dxtension 11d terminat' in a beveled end. The short 'aw 8d has a beveled end paralleling the en of the projection 11d. This gives to the stringer back of the rib a slight bend and consequently assists in securing the stringer to the member;

A slider 13 (See Figs. 11, 12 and 13) has a confining plate 14, a spreader 15 and a plate 16, the spreader connecting these plates. The plate 14 is provided wlth clos mg flanges 17 of usual form except that the fla are somewhat deeper than the ordinary flan and engage the ends 76 of the jaws 7 o the fastener members. The

.plate 16 is fiat and narrower than the bottom plate 14. By making the upper plate 16 flat the jaws engaging this upper plate are perfectl to move and accommodate themselves .in and out as they are guided by the guide flange 17. Thus friction is ve rnuc reduced. The-platev 16 is also mu .strmge narrower than the lowerplate 14. This is made practical because the guiding ends of the members having the greater ofl-set are enga ed for spreadin and closing the mem rs so that all t at the opposite or narrower side of the slider has to do is to retain the members between'the plates and in as much as the upper jaws 8 are comparatively short the spreader plate can, to

advantage, made correspondingly narin Tn Fi 15 a plate 20, which is the narrower p ate, is provided with the closing flanges and a spreader 21 'oins this plate with a flat plate 22. A tab fastening lug 23 is secured to the flat plate 22.

In the structure shown in Fig. 16 both lates 24 and 25 are provided with closing anges, the plate 24 being narrower than the plate 25. These platesare connected by a spreader 26 and a tab fastening lug 27 is secured on the plate 24.
